Turkish Prime Minister Ahmet Davutoglu has said Turkey will not apologise for bringing down a Russian jet on the Syrian border.
Mr. Davutoglu said the incident was unfortunate but that Turkey had a right and duty to protect its airspace.
The body of a pilot killed in the incident is being flown home.
Meanwhile, a Russian military spokesman said today that Russia has armed its Su-34 fighter jets over Syria with air-to-air missiles for the first time.
While he did not mention which particular threat the missiles were meant to counter, it comes six days after the Russian plane was shot down by Turkey.
